Bosch D126 12 V 7 Ah UPS Battery

This sealed lead-acid battery is a direct replacement for Bosch D126 UPS units. It uses AGM technology to provide maintenance-free standby power for servers and network equipment. The non-spillable design allows safe operation in any orientation. It is built for continuous float service in rack-mounted or tower UPS systems.

Capacity and runtime limits

The 7 Ah rating supplies enough reserve for typical network loads during short outages. Extended runtime demands will exceed the available capacity and require additional battery modules. Gas recombination above 90 % reduces water loss over the 4-7 year design life. Deep discharge cycles will shorten the expected service interval significantly.

12 V 7 Ah AGM specification

The 12 V nominal voltage and 7 Ah capacity must match the original UPS specifications exactly. Verify the physical dimensions and terminal layout against the unit being replaced before installation. This battery is not suitable for cyclic applications or automotive starting duties. Incorrect voltage or capacity will cause UPS fault conditions.

Questions about this item

Will this 12 V 7 Ah battery fit the Bosch D126 slot in my existing UPS?

The unit is built as a 100% OEM replacement for the Bosch D126, so it matches the original voltage and capacity for a direct swap.

How can I verify the AGM battery is working correctly after installation?

After charging, the UPS should hold its rated runtime and show no fault codes; the sealed AGM design means no electrolyte checks are needed.

Does the package include cables or mounting hardware, or must I buy them separately?

Only the replacement battery is supplied; any cables, brackets or terminal adapters required by your UPS model must be sourced separately.
